EXALTATION OF CO2 ABSORPTION IN BUFFER CO 3 HCO3 SOLUTIONS BY SUGARS OR GLYCERIN/

The absorption of CO2 in Na2CO3/NaHCO3 buffer solutions (0.5M-0.5M) ha s taken place inthe presence of saccarose, glucose, fructose or glycer in, using a wet wall column and in the conditions for a pseudofirst or der reaction. The experimental results have been analyzed from the poi nt of view of Higbie theorie for a pseudofirst order reaction, and the overall kinetic coefficients for every solute and concentration have been determined. The obtained values were correlated with the solute c oncentration by means of similar expressions to the given in the liter atur for sodium arsenite, current catalyst in CO2 absorption in buffer solutions of sodium carbonate/bicarbonate. The values of the respecti ve adjustment parameters k(0) an k(cat) are supplied. There have also been evaluated the respective exaltation factors and they have been co mpared with the ones obtained by means of theoretical patterns.
